Bentoshield Max LM – Geocomposite Waterproofing
Bentoshield Max LM
BentoShield Max LM is a geosynthetic clay liner produced by sandwiching natural sodium bentonite granules between high-strength geotextile layers. Upon contact with water, it swells to form an effective, low-permeability hydraulic barrier, preventing water from reaching structural elements.
Developed specifically for waterproofing applications on foundations, retaining walls, and underground structures, BentoShield Max LM delivers reliable performance in projects subject to moderate to high hydrostatic pressure. Thanks to its structure, which forms a mechanical bond with the concrete, it restricts water migration between the waterproofing layer and the structure while providing long-lasting protection.
Thanks to its high bentonite content, durable geocomposite structure, and mechanical strength, it maintains system integrity against punctures, tears, and external impacts that may occur during application. With its easy-to-apply nature, it offers a reliable, cost-effective, and long-lasting waterproofing solution for foundations and retaining walls.
Unique solutions for foundation and curtain wall insulation
Bentoshield MAX LM is a composite waterproofing material formed by combining polymer-modified sodium bentonite granules with high-strength pure polypropylene woven and non-woven geotextile materials using a patented needle-punching method, and integrating them with a PE film layer. Bentoshield MAX LM provides waterproofing even at depths of 70 meters, ensuring waterproofing even under the most challenging conditions. Bentoshield MAX LM is a globally recognized waterproofing material, being the first waterproofing material to hold BBA certification. It eliminates the need for a protective sheet, geotextile, or brick wall in double-sided curtain installations, ensuring the backfill is compacted in an orderly manner.
Bentoshield Max LM – Geocomposite Waterproofing Functions
Bentoshield Max LM offers superior waterproofing performance through its polymer-modified sodium bentonite technology and durable geocomposite structure. Upon contact with water, it forms an active hydraulic barrier that effectively restricts water migration into structural elements. Providing reliable protection against high hydrostatic pressure in foundation and retaining wall waterproofing applications, the system forms a mechanical bond with the concrete, ensuring long-lasting and continuous waterproofing performance. Its design eliminates the need for protection boards or additional geotextiles, thereby simplifying the application process while providing an economical and permanent waterproofing solution.
High-Pressure Insulation
Thanks to its high bentonite content, it provides reliable waterproofing for foundation, retaining wall, and deep excavation applications subject to hydrostatic pressure.
Active Hydraulic Barrier
Upon contact with water, bentonite swells to form an active, low-permeability barrier, limiting the passage of water to the structural elements.
Foundation and Shear Wall Protection
It contributes to protecting the structure against the effects of water and moisture by forming a continuous insulation layer on foundation and reinforced concrete shear wall surfaces.
